Don't worry where aircraft are based. You are wayyyy too far off to even remotely worry about it. It will have changed three times by the time you get even close to applying.
Also, I know I didn't mention it, but realize that getting hired by a legacy (United, AA, Delta etc) is still a long shot. Even though they are hiring a lot right now, many, many pilots with thousands of hours (think 10 years and 10,000 hours experience) are still desperately still trying to just get an interview.......
